The authorities want to increase the inflow and outflow through the Hvide Sande Sluice to the Ringkøbing Fjord. At present, some very large erosion holes in the Hvide Sande Channel have been developed. How the holes will develop in the future has been estimated by a combination of desk study, full-scale measurements, and DHI's in-house refined flow code, NS3.

The plan layout of the new protection structures for Thorsminde Harbour has been optimised by use of 2D numerical modelling tools (especially MIKE 21 CAMS) from the point of view of minimising sedimentation of the harbour entrance and maintaining a safe minimum depth.

The Fehmarnbelt Fixed Link is undergoing comprehensive Environmental Impact Assessment investigations. One of the components is the Coastal Morphology Impact Assessment. Two alternative layouts are going through the EIA investigations, a bridge alternative and a tunnel alternative, respectively.

2D numerical modelling study for the design of a nourished beach inside the Lorient estuary. The investigations include modelling of nearshore wave transformation, hydrodynamic flow and sediment transport.

Dadar - Prabhadevi Beach in Mahim Bay, Mumbai is one of few public beaches in Mumbai. The quality and the area of the beach have been steadily degrading due to in-appropriate building of houses and compound walls too close to the beach, combined with the natural erosion of the beach. A group of concerned citizens represented by P.K. Das & Associates has prepared a restoration project, which includes nourishment of the existing beach in order to widen the beach area. P. K. Das & Associates has commissioned DHI Water & Environment (DHI) to make a coastal study including wave and hydraulic modelling with the objectives of studying beach stability and providing design data for the new beach. Recommendations of grain size, beach slope and beach orientation for the new beaches has been listed in the report.
